Description

Technical Field

[0001] This utility model relates to the field of transportation vehicle technology, and in particular to an instrument display structure and an electric vehicle. Background Technology

[0002] In the field of electric vehicle instrument displays, LED backlighting technology has long faced the challenge of balancing ambient light interference and visual experience. Early instruments generally adopted a high color rendering index (CRI) green LED solution (color temperature 5500K, CRI Ra>85). Its advantage lies in the high sensitivity of the human retina to green light, which can achieve a minimum contrast ratio of 20% under sunlight. However, this technology has inherent limitations, such as insufficient color gamut coverage of traditional green light, resulting in a monotonous color hierarchy on the interface, which is difficult to meet the demands of users for high-end texture in the context of consumption upgrading.

[0003] When the industry attempted to switch to white LED technology (color temperature 6500K, Ra≥75), it was found that because the filter film was only fixed on the light shield, there was a gap between the filter film and the cover. Traditional white LED instruments had problems such as blurry display and uneven brightness in sunlight. Drivers had to frequently adjust their viewing angle to read the information, which affected driving safety. Utility Model Content

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0027] The first aspect of this utility model provides an instrument display structure, such as... Figure 1 As shown, it includes an instrument housing 1, a filter membrane 2, and a light source assembly 3, both of which are installed inside the instrument housing 1;

[0028] The instrument housing 1 has a display area 112, a filter film 2 is located between the display area 112 and the light source assembly 3, and one side of the filter film 2 is connected to the light source assembly 3, while the other side is bonded to the inner wall of the display area 112.

[0029] by Figure 1 Taking the first aspect of this utility model as an example, in the instrument display structure provided, the lower side of the filter film 2 is connected to the light source component 3, and the upper side of the filter film 2 is bonded to the inner surface of the display area 112 in the instrument housing 1. This results in a better adhesion between the filter film 2 and the display area 112, avoiding gaps between them, optimizing the light transmission effect, effectively alleviating the problems of blurred display and uneven brightness caused by light scattering in traditional instruments, effectively improving the light focusing of the instrument display area, and significantly enhancing the clarity of text and images.

[0030] Among them, the filter film 2 can be made of high light transmittance optical materials, such as acrylic or PET (Polyethylene terephthalate) film.

[0031] To ensure a tight fit between the filter film 2 and the instrument housing 1, and to prevent air bubbles or gaps from affecting the optical effect, a layer of low-volatility, high-adhesion optical adhesive, such as UV (Ultraviolet) curing adhesive, can be uniformly coated on the surface of the filter film 2. Then, the instrument housing 1 and the filter film 2 are pressed tightly together, allowing the light transmission path of the filter film 2 to directly penetrate the display area 112 of the instrument housing 1.

[0032] The aforementioned display area 112 can also be made of light-transmitting optical materials.

[0033] In an optional embodiment, the instrument housing 1 includes an upper cover 11, a lower cover 12, and a fastener 13. The fastener 13 passes through the lower cover 12 and connects to the upper cover 11. The upper cover 11 has a display area 112.

[0034] In the above embodiments, both the upper cover 11 and the lower cover 12 are open shells with their openings facing each other, and the sidewall of the upper cover 11 covers the outside of the sidewall of the lower cover 12. The fastener 13 connects to the upper cover 11 by penetrating the lower cover 12. Compared to the traditional snap-fit ​​assembly method, this provides better mechanical fixing, not only improving the overall structural strength of the instrument cover 1 and forming a complete and stable instrument shell structure to achieve light transmission and instrument protection functions, but also enhancing its reliability in extreme environments. For example, in high or low temperature environments, the material of the instrument cover 1 may expand or contract. Snap-fit ​​assembly is prone to loosening or increased gaps due to dimensional changes, while the fastener 13 can adapt to these changes by increasing the preload, keeping the upper cover 11 and the lower cover 12 tightly connected. Under vibration conditions, such as the bumps during vehicle movement, the fastener 13 can effectively prevent relative displacement between the upper cover 11 and the lower cover 12, avoiding loosening or detachment.

[0035] Therefore, the connection between the upper cover 11 and the lower cover 12 via the fastener 13 can effectively avoid the halo defect caused by the gap between the upper cover 11 and the lower cover 12 due to the traditional snap-fit ​​assembly. In conjunction with the adhesion of the filter film 2 to the inner wall of the display area 112, the contrast and visual effect of the display area 112 are improved. Especially in bright environments, users can still have a good visual experience.

[0036] Tests showed that the instrument's display structure maintained structural integrity and stable optical performance within a temperature range of -20℃ to 60℃ and under vibration conditions with 3G acceleration, meeting the dual requirements of high-definition display and stable operation.

[0037] like Figure 1 As shown, the upper cover 11 can be fastened to the outside of the lower cover 12, providing better waterproofing.

[0038] In addition, fastener 13 can be a screw or a pin, etc.

[0039] In an optional embodiment, the fastener 13 is preferably a screw to facilitate the assembly and disassembly of the upper cover 11 and the lower cover 12.

[0040] If the components inside the instrument cover 1 need to be replaced or adjusted, the screws can be quickly removed and reinstalled without causing permanent damage to the instrument cover 1 or affecting the quality of reassembly.

[0041] The screws can be Phillips head screws or hex socket screws, etc.

[0042] In an optional embodiment, the filter film 2 and the light source assembly 3 are sandwiched between the upper cover 11 and the lower cover 12.

[0043] In the above embodiments, after installation, the upper cover 11 and the lower cover 12 can also limit the filter film 2 and the light source assembly 3 in a direction perpendicular to the display surface in the display area 112, ensuring the assembly stability of the two in the instrument housing 1. The upper cover 11 can be tightly pressed with the filter film 2, which can also make the structure inside the instrument housing 1 more compact.

[0044] In an optional embodiment, the upper cover 11 has a connecting portion 111 protruding towards the lower cover 12, the connecting portion 111 has a connecting hole 1111, and the fastener 13 passes through the lower cover 12 and is connected to the connecting hole 1111.

[0045] In the above embodiment, the connecting part 111 is columnar and is arranged perpendicularly to the top wall of the upper cover 11, and the opening of the connecting hole 1111 faces the lower cover 12. The arrangement of the connecting part 111 can form a connecting hole 1111 with a longer axial length, increase the mating area between the fastener 13 and the upper cover 11, ensure the connection strength, and at the same time eliminate the need for a thicker design for the display area 112 of the upper cover 11.

[0046] Based on the above embodiments, the connecting part 111 can also cooperate with the lower cover 12 to achieve initial positioning when the upper cover 11 and the lower cover 12 are fastened together. Optionally, the lower cover 12 has a positioning protrusion protruding towards the upper cover 11, the position of the positioning protrusion corresponding to the position of the connecting part 111, the top surface of the positioning protrusion has a positioning groove, and the bottom of the positioning groove has a through hole. When the upper cover 11 and the lower cover 12 are mated, the connecting part 111 can extend into the positioning groove to facilitate the initial positioning of the upper cover 11 and the lower cover 12. At this time, the connecting hole 1111 is aligned with the through hole, and the installer can pass the fastener 13 through the through hole and connect it into the connecting hole 1111 to realize the assembly of the upper cover 11 and the lower cover 12.

[0047] Therefore, the above-described embodiments can reduce the docking time for installers when docking the upper cover 11 and the lower cover 12, significantly improve assembly efficiency, and shorten the development cycle.

[0048] In an optional embodiment, multiple connecting parts 111 are configured, each connecting part 111 passing through the filter film 2 and the light source assembly 3, and multiple fasteners 13 are configured to be connected to the connecting parts 111 one by one.

[0049] In the above embodiments, the upper cover 11 and the lower cover 12 can be fixed from different positions by multiple fasteners 13, forming a stable outer shell structure.

[0050] In alternative implementations, such as Figure 1As shown, the light source assembly 3 includes a light source structure 31 and a light-blocking plate 32. One side of the light-blocking plate 32 is connected to the filter film 2, and the other side is connected to the light source structure 31. The light source structure 31 has multiple light-emitting points 311. The light-blocking plate 32 has multiple light-transmitting grooves 321 that are correspondingly arranged around the multiple light-emitting points 311. The openings of the light-transmitting grooves 321 face the filter film 2.

[0051] In the above embodiments, the light-blocking plate 32 is made of an opaque material, such as black PC (Polycarbonate) or ABS (Acrylonitrile Butadiene Styrene plastic) engineering plastic, to prevent the light emitted by the light-emitting point from scattering in all directions. The light-transmitting groove 321 is used to guide the light emitted by the light-emitting point 311 within it to the display area 112, confining the light emitted by the light-emitting point 311 within a predetermined path, effectively preventing light scattering and crosstalk, and improving the brightness uniformity and clarity of the instrument display area.

[0052] In an optional embodiment, the filter film 2 is bonded to the light-blocking plate 32, and the adhesive used for bonding may be, but is not limited to, a UV-curable adhesive.

[0053] In the above embodiments, the light-blocking plate 32, the light-filtering film 2 and the upper cover 11 are integrated into one package, so that the thickness of the combined module is less than 5mm, which can achieve curved surface fitting (minimum bending radius 8mm) and can be adapted to irregular spaces such as vehicle dashboards.

[0054] The filter film 2 can be made of a high-transmittance optical material. The above-described embodiments can further optimize the light transmission path and prevent light from overflowing from the non-display area.

[0055] Specifically, when bonding the filter membrane 2 to the light-blocking plate 32, a vacuum adsorption bonding process can be used, and negative pressure equipment can be used to remove air to ensure that the filter membrane 2 and the light-blocking plate 32 are completely bonded.

[0056] In an optional embodiment, the light source structure 31 includes a circuit board 312, on which a plurality of light-emitting points 311 are provided, and the circuit board 312 is fixedly connected to the light-blocking plate 32.

[0057] The fixed connection between the circuit board 312 and the light shield 32 can ensure the stability of their relative positions and facilitate the tight fit between the circuit board 312 and the light shield 32.

[0058] In an optional implementation, the circuit board 312 can be connected to the light shield 32 by screws or clips. The purpose of the light shield 32 is to isolate the light emitted by each light source 311, prevent light scattering and crosstalk, and ensure that the light propagates along a predetermined path.

[0059] Using the above method requires setting multiple screws or clips between the circuit board 312 and the light shield 32 to fix them together and reduce the gap between the circuit board 312 and the light shield 32.

[0060] For example, the circuit board 312 has multiple slots, and the light shield 32 has corresponding buckles that fit into each slot. The relative positions of the two are fixed by the snapping of the two.

[0061] In other embodiments, the circuit board 312 is soldered to the light shield 32.

[0062] By using welding and vacuum adsorption bonding between the filter film 2 and the light shielding plate 32, the assembly efficiency of the instrument display structure can be effectively improved, effectively solving the problem of time-consuming traditional assembly methods.

[0063] Among them, the circuit board 312 serves as the core carrier of the instrument's electrical functions. In addition to installing LED beads, it can also integrate circuit components and circuit layout. Through circuit design, the instrument's data processing, signal transmission, and light source control functions can be realized.

[0064] In addition, each light-emitting point 311 can be a single LED, and multiple LEDs can be configured to display different fonts in the display area 112 by flashing different LEDs.

[0065] The aforementioned LED beads are white LED beads. The high color temperature (5500K) of the white LED beads, combined with the setting of the filter film 2, can effectively improve the clarity of the pixel boundary, ensuring that the characters / graphics can still be recognized in sunlight.

[0066] In addition, since the clarity of the display area 112 is effectively improved, the power consumption can be effectively reduced compared with traditional backlighting. The typical operating current is <20mA / LED, and the total screen energy consumption is ≤3W (7-inch screen) after being combined with the constant current drive circuit.

[0067] The 7° tilted installation structure, when used with filter film 2 (reflectivity <1.5%), can eliminate more than 85% of specular glare and ensure brightness uniformity >90% at a wide viewing angle of 160°.

[0068] The second aspect of this utility model provides an electric vehicle, which includes the aforementioned instrument display structure.

[0069] The electric vehicle provided in the second aspect of this utility model has the instrument display structure provided in the first aspect of this utility model, and thus has all the beneficial effects of the instrument display structure provided in the first aspect of this utility model.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
